How does water act as an agent of soilerosion?
When it rains heavily and there is flooding, water acts as an agent of soil erosion by carrying away the top layer of soil.
How forests prevent soil erosion?
(a)The roots hold the soil in place. (b)The leaves of trees act as an umbrella reducing the force of raindrops hitting the soil.
What does not act as agent for eroding rock and transporting sediment?
Agents for erosion and transporting sediments include gravity, wind, water (including currents), or ice. Other forces in nature do not act in the same way, for example, lava.
Which of these choices is a goal of the Soil and Water Resources Conservation Act?
To assess the conservation of soil and water resources on private lands
Why does the cutting down of trees lead to soil erosion?
In open country, trees act as windbreaks and keep wind from blowing away topsoil and their roots prevent soil from being washed away from heavy rains. Tree roots also help store water in the ground.
How does water act as an agent of soilerosion?
When it rains heavily and there is flooding, water acts as an agent of soil erosion by carrying away the top layer of soil.
Is soil erosion the breaking down of plants and animals in the soil?
No. Soil erosion is the act of soil being carried away to another location by wind and/or water.
How does water and wind act as an agent of erosion in the desert?
It blows the sand aroud. Or the water can wash it away. Such as a sand storm.
How do crops prevent weathering and erosion?
Crops and other vegetation act to reduce weathering and erosion in a number of ways. 1. Their leaves or stalks act to intercept rain drops reducing the of amount of water reaching the soil and also it's velocity. 2. Their roots act to mechanically bind the soil together. 3. Their roots also draw water from the soil. This can lead to negative pore water pressures (known as soil suction) which in turn helps the individual soil grains bind together.
How do plants control erosion from water runoff?
Plants help to check soil erosion considerably. During flood or excessive rain, the soil gets washed away by the flow of water. However, deep rooted plants help the soil not get washed away by the water pressure, thereby slowing down the process of soil erosion. Therefore, planting of deep rooted trees are advisable along the river shore.
How does wind act in erosion?
Wind is an agent of erosion. It is responsible for moving material from one place to another place.
How do humans affect erosion by logging?
Human beings may cause erosion by activities such as farming or games. They may also cause erosion by cutting down trees and other vegetation that act as windbreakers.
Does soil erosion hurt plants?
Yes. Soil erosion is the act of wind and water taking away the nutrients and organic matter that plants need to survive if not thrive. Without this, it not only "hurts" plants, but kills them to the point where no plants will grow in a particular area anymore.
Why do farmers plant a row of trees to conservation of soil?
the trees act as a windbreak reducing soil erosion caused by blowing wind
How forests prevent soil erosion?
(a)The roots hold the soil in place. (b)The leaves of trees act as an umbrella reducing the force of raindrops hitting the soil.
How do plants act as agent of both chemical and mechanical weathering?
A plant can act as an agent of mechanical weathering by simply growing next to something. The plant will rub against it and in some cases grow in any openings in the material. Tree roots can grow into the cracks in boulders and ledges, widening these cracks and ultimately contributing to the break-down of these structures. Plants also produce oxygen gas which contributes to chemical weathering through the formation of metal oxides. Tree roots also take nutrients and minerals from the soil, ultimately leaving them on top of the ground and subject to erosion forces.
What human activity does not increase erosion?
Anything that doesn't produce an environment with looser soil, less water, or higher winds (directly) will not increase erosion on a visible scale. If you count walking and breathing as erosion, then every movement and act a person does will increase erosion because it will displace molecules and particles, such as stubbing your toe.
